“It's not an easy thing to have to go through, but it's only an hour and a half of our lives, so we can get through it I think.

“It is weird to look across the net and see your brother because you want each other to win every time they step on the court.

Former world number one Andy has also revealed he will play no part in the US Open, with the 2012 champion deciding against playing doubles in New York.

Instead, he intends to play singles at next week’s ATP event in Winston-Salem before potentially entering a tournament on the Challenger Tour during the final major of the year.

“I'm not going to play doubles at the US Open,” the 32-year-old told BBC Sport. “My goal is to get back playing at the level that I want to on the singles court.

“I've decided that I need to focus all my energies on that right now. The US Open, doubles and mixed, can be another couple of weeks that you are slowing things down.

“It doesn't feel like I need to play the main draw of every single tour event. I've hardly played the last couple of years and, having discussed with my team, after this week I think doubles is done for me for the time being.

“I need to focus my mind on getting matches on the singles court. There aren't many tournaments between now and the end of the year.”
